setting windows environment variables

setting windows environment variables

[Jason Joines]

	I have a Cygwin BASH script which takes user input, uses ldapsearch, 
etc., to set a bunch of environment variables.  I can then use these 
from bash with no problem.  I would also like to make these environment 
variables available to the windows command interpreter.
	Is there anyway to do this?
	Also, is there a BASH equivalent of the windows cmd start command that 
lets you start many processes without having to wait on each to finish?

Thanks,

Jason Joines

Only if the windows command interpreter is a child of the bash process you
run from.  Otherwise, your best bet is to export the variables as some
batch file and run that in the windows command interpreter.

How about 'cygstart'?

	Just found cygstart was in cygutils and used it.  The --hide option was 
just what I needed.

Try setx:
http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/setx-o.asp

You can change Windows environment variables from the command line, so
that you can call setx and change them from bash scripts.  It works
excellent for me to share a single ssh-agent Windows-wide. :)

You can use it only on NT/2000/XP, perhaps.
I'm not sure what's available on Windows 9X/ME.

``cygstart'' should be what you are looking for.

so, maybe

nohup smbmount //whatever /whereever > /dev/null 2>&1 &

should do, still in an portable way...

Re: setting windows environment variables

[Jason Joines]

	Unfortunately, it won't be used on a real operating system, just 
windows.  I write BASH scripts for Linux daily and have tried to use the 
& in this situation but the behavior doesn't seem to be the same.
	We have an odd situation with some user's in one directory with one 
username and another with a different username and some in just one or 
the other.  Long story...
	I needed a way to obtain drive mappings from a directory based on user 
input on a standalone PC.  Being familiar with BASH on Linux I stuck 
Cygwin BASH on windows 2000.
	The script prompts the user for their username and password, then uses 
ldapsearch to get their home directory path, then uses windows "net use" 
to map H: to that path and a few other drives.  The shares are on a very 
unstable active directory/windows 2003 setup.  Again, long story...  If 
I just call the four "net use" commands one at a time waiting for each 
to complete before it attempts the next, it will at times take over 5 
minutes.  Using the & after the "net use" commands does what I want with 
starting all the mappings without waiting on completion but my BASH 
window wont' go away until they have all completed.
	On Linux, something simple like:
#!/bin/bash
smbmount //srv1/share1 ~/share1 &
smbmount //srv1/share2 ~/share2 &
smbmount //srv1/share3 ~/share3 &
smbmount //srv2/share4 ~/share4 &
exit

would work just fine.  Any ideas on how to accomplish the same thing here?

Thanks,

Re: setting windows environment variables

[Robert Pendell]

And it is compatible for use on *bsd, linux, and unix.  So if you are
writing a script to be used on a real *nix or *bsd system then that
would be the one to use.

[Morche Matthias]

...to set environmental variables for windows you can use regtool...
But in that case they get persistent...

...and the simplest equivalent to start is using & to background the command...
